I am a singer myself. I am currently recording my first studio album which is an adult contemporary album with songs from all genres.
Though I have a bachelors and masters in vocal performance, meaning I'm classically trained and have had a career in classical music, I teach a technique that is for all singers.
Because I sing many types of music, I sing each type with the same vocal technique, i.e. correct breathing, posture, sound placement and exercises that can double your voices potential!
It's just about healthy correct singing. Doesn't matter what genre you belong in. And I share that technique with my students.
